Mechanochemically sulfured FeS_(1.92) as stable and efficient heterogeneous Fenton catalyst

Fenton reaction is one of most promising approaches for efficient removal of various robust organic pollutants in wastewater,however it faces several intrinsic challenges such as acidic condition,sludge waste and sensitive to sulfide-containing compound.Here we reported a novel FeS_(1.92) as an efficient and sulfide resistant heterogeneous Fenton catalyst under mild condition.This novel FeS...  (本文共4页) 阅读全文>>

Fabricating Fe_3O_4-schwertmannite as a Z-scheme photocatalyst with excellent photocatalysis-Fenton reaction and recyclability

Here we reported an effective method to solve the rate-limiting steps, such as the reduction of Fe~(3+) to Fe~(2+) and an invalid decomposition of H_2O_2 in a conventional Fenton-like reaction. A magnetic heterogeneous photocatalyst, Fe_3O_4-schwertmannite(Fe_3O_4-sch) was successfully developed by adding Fe_3O_4 in the formation process of schwertmannite. Fe_3O_4-sch shows excellent electrons transfer ability and hi...  (本文共10页) 阅读全文>>
